I've looked into bootloaders in the past primarily to be able to =20
program with less pins.  However, the usual TX/RX pins are in use for =20
something else in my app, so they haven't been a good option.  =20
One-wire would be really nice for this, but the PIC would have to be =20
the master, and the code storage device (since I don't want to call it =20
a programmer here) would have to be the slave. Anyone ever seen one of =20
these?

Cheers,
-Neil.
